Applets, Servlets and JSP
Java Programming : applets, servlets and JSP. SR03 Dritan Nace A summary of Java Java is a language developed by Sun, which is designed to be object oriented and Simple, robust and secure, independent of hardware architectures and Multitasking. Object oriented and simple : Simpler than C++, transparent memory managment… Robust et secure : Data typing is extremely strict. For applets, it is in principle impossible to access the resources of the host machine. Independant of hardware architectures : The compiler generates a universal code : the « byte-code ». An interpreter which is specific to the host machine, « virtual machine », executes the programs. Multitasking : Java seemingly allows execution of several processes. In reality, a time slot is given to each process on the processor (Multithreaded). J2SE versus J2EE J2SE (standard edition) contains the basic usable components from both the client and server side, – GUI, AWT/Swing for applications (client) or applets. Currently J2SE v1.6 (ou V6) J2EE (enterprise edition), is in a certain sense an extension of SE, designed for server side programming – Servlets, JSP, EJB, etc. • Currently J2EE v1.4 Java and object oriented programming • Classes, and objects – The objects include data and processing for the data. Communication is done via messages (methods). – A class corresponds to an abstract model for object construction. A class is made up of: • attributes (static part) • Methods (dynamic part), which define the behaviour. – Inheritance : the « is a » relationship : a car is a vehicule, – Polymorphism : the same message can be recognised by several objects and entail different behaviour. Portability: JVM The compiler compiles the java source in byte code : javac car.java => car.class Then, java is the name of the program which will interpret the generated byte code. -
Abstract Window Toolkit Overview
In this chapter: • Components • Peers 1 • Layouts • Containers • And the Rest • Summary Abstract Window Toolkit Overview For years, programmers have had to go through the hassles of porting software from BSD-based UNIX to System V Release 4–based UNIX, from OpenWindows to Motif, from PC to UNIX to Macintosh (or some combination thereof), and between various other alternatives, too numerous to mention. Getting an applica- tion to work was only part of the problem; you also had to port it to all the plat- forms you supported, which often took more time than the development effort itself. In the UNIX world, standards like POSIX and X made it easier to move appli- cations between different UNIX platforms. But they only solved part of the prob- lem and didn’t provide any help with the PC world. Portability became even more important as the Internet grew. The goal was clear: wouldn’t it be great if you could just move applications between different operating environments without worr yingabout the software breaking because of a different operating system, win- dowing environment, or internal data representation? In the spring of 1995, Sun Microsystems announced Java, which claimed to solve this dilemma. What started out as a dancing penguin (or Star Trek communicator) named Duke on remote controls for interactive television has become a new paradigm for programming on the Internet. With Java, you can create a program on one platform and deliver the compilation output (byte-codes/class files) to ever yother supported environment without recompiling or worrying about the local windowing environment, word size, or byte order. -

That is why when you install Java a notification and warning window appears. All versions of Java from 8 u201 onwards not intended for personal use are payable. For this reason, we suggest you do not update Java 8 to a newer version for work purposes. If you want a newer version of Java 8, install OpenJDK 8 and IcedTea. Also, do not install Java 8 on new computers (clients), but install OpenJDK 8 with IcedTea support. 2 OpenJDK distribution OpenJDK 1.8. build for Windows and Linux is available at the link https://github.com/ojdkbuild/ojdkbuild.

Before the Web There Was Gopher
Before the Web There Was Gopher Philip L. Frana Charles Babbage Institute The World Wide Web, universally well known today, was preceded by an efficient software tool that was fondly named Gopher. The Internet Gopher, much like the Web, enabled users to obtain information quickly and easily. Why, then, did it disappear but the Web did not? Gopher faded into obscurity for two main reasons: hypertext and commerce. Before the Web there was Gopher, a nearly anymore, despite the efforts of a handful of defunct Internet application protocol and asso- individuals to revitalize the protocol. Why did ciated client and server software.1 In the early Gopher fail? Many Gopher aficionados have a 1990s, Gopher burrowed a crucial path ready answer: pretty pictures.

In order to do Java detection, you will need 2 things: 1) download the getJavaInfo.jar applet along with a few Java detection examples. The jarfile (Java ARchive file) is used by PluginDetect in order to accomplish Java detection. 2) download the PluginDetect script itself. The PluginDetect script generator will allow you to customize the PluginDetect script to include whatever features you desire. That being said, I would still recommend that you read thru most of this page before creating your own Java detection code. A brief introduction to Java detection PluginDetect uses a number of different methods when trying to detect Java in your browser. These Java detection methods can be divided into 2 groups: a) the non-applet methods and b) the applet methods. -
